Look at it this way. If you have to ask, it shows that you have no strategic planning.....you will be doomed to failure. Ads. - you attract them , and they pay you only when you have reached a predetermined number of "Hits"..... So, how are you going to finance the upkeep of the site in the meantime ? What make you think that you can compete with Facebook and others ?

Addendum:

However, you may try to convince friends and relatives to provide you with loans, small individual cash loans which may add to to a large amount. Someone may also provide you with venture capital. You may yet succeed if the contents of the web site are good and appropriate for today's youth......but they would have to be something unique and special....something that can become the "talk of the town"... If you can do that, then advertisers will queue up and beg you to put their ads on your site....in fact, your main revenue will be from the ads.....
